The Impact of Natural Zeolite (Clinoptilolite) in Water on The Blood Parameters of Common Carp (Cyprinus carpio L.) In a Recirculation Aquaculture System

Abstract

Abstract The aim of conducting this study was to evaluate the use of added natural zeolite (clinoptilolite) in common carp fingerling (Cyprinus Carpio L.) breeding ponds and to demonstrate its effect on blood characteristics, This study was conducted in the fish laboratory of the Department of Animal Production - College of Agriculture - Anbar University – Iraq, For 12 weeks with an initial weight of the fish reaching (25 ± 1) gram, The study included 7 treatments, each treatment was divided into 3 replicates, in each replicate (10 fish), the first treatment (control treatment), Zeolite was added to the rest of the treatments in two ways, the first way was (add inside the filter) in proportions (5, 10, 15) g/L for the second, third, and fourth treatments, respectively, In the second way, add zeolite (inside the rearing ponds with plastic mesh bags) in proportions (5, 10, 15) g/L for the fifth, sixth, and seventh treatments, respectively, The results of the study showed a significant increase for treatments T2 On the rest of the experimental parameters in In the values of both (RBC), (MCHC) It also recorded the highest value for (PCV),(Hb) Compared to the rest of the transactions Including transaction control.
